We look at the division of 51835072 by 808 
The aim is to understand the frequency of 808 in 51835072.

Moving on to step 1:
When dividing 5 by 808, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 808

On to step 2:
The number 808 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 808

On to step 3:
The number 808 fits into 518 0 times, leaving a remainder of 518.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 518, we end up with 518.
Bring next digit (3) of the dividend behind the 518 and repeat the process: 5183 / 808

Advancing to step 4:
If we divide 5183 by 808, we get 6 and a remainder of 335.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4848 from 5183 and we're left with 335.
Fetch the next digit (5) from the dividend, attach it to 335 and continue: 3355 / 808

Moving on to step 5:
808 goes into 3355 4 times with a remainder of 123.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 3232 from 3355 leaves us with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 808

Step 6:
The number 808 fits into 1230 1 times, leaving a remainder of 422.
Put 1 as the next digit of the answer. 
Result so far: 641.0
The remainder is 422 after subtracting 808 from 1230.
Bring next digit (7) of the dividend behind the 422 and repeat the process: 4227 / 808

Moving on to step 7:
4227 divided by 808 is 5 with a remainder of 187.
The number 5 becomes the next digit in our result. 
Result so far: 6415.0
Deduct 4040 from 4227 and we're left with 187.
Append the next digit (2) from the dividend to 187 and continue with: 1872 / 808

Step 8:
1872 divided by 808 is 2 with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 64152.0
Subtract 1616 from 1872 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 9:
The number 808 fits into 2560 3 times, leaving a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 64152.3
Deduct 2424 from 2560 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
If we divide 1360 by 808, we get 1 and a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 64152.31
The remainder is 552 after subtracting 808 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 11:
808 goes into 5520 6 times with a remainder of 672.
The next digit of our result is 6. 
Result so far: 64152.316
If we take 4848 away from 5520, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 12:
808 can be fit into 6720 8 times, resulting in a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 64152.3168
The remainder is 256 after subtracting 6464 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
808 can be fit into 2560 3 times, resulting in a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 64152.31683
If we take 2424 away from 2560, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
When dividing 1360 by 808, we get 1 with a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 64152.316831
The remainder is 552 after subtracting 808 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 15:
When dividing 5520 by 808, we get 6 with a remainder of 672.
Record the quotient 6 as the next digit in the result. 
Result so far: 64152.3168316
If we take 4848 away from 5520, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 16:
If we divide 6720 by 808, we get 8 and a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 64152.31683168
If we take 6464 away from 6720, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 64152.31683168 with a remaining 2.56e-07.
